Whenever I click "Minecraft Realms" on the title screen my realm does not show up at all. Infact my whole game crashes trying to render the screen. This only occured on realms, that's it!

When Minecraft 1.16 was released I had signed out of my Optifine 1.15.2 account and booted up the latest release of the game (1.16). I wanted to go on my realm I own to explore the update with my friends, but every time I click "Minecraft Realms" nothing pops up, just the dirt background and the logo on top. Within 30 seconds my game would crash and says that it crashed "Trying to Render the Screen". I tried again and again several times but the same result occurred every time. I play on a Mac OS with pretty good WIFI so one would think it would work. I then tried again back on my 1.15.2 Optifine account and all it said was "Realm(0):".
